AUTOMATIC PUMP.

To all whom it may concern:

Be it known that I, CHARLES "W. MoGoNI- cm a citizen of the UnitedStates,.residing at Seattle, in the county of King and State of 1Vashington, have invented a new and useful Automatic Pump, of which thefollowing is a specification.

This invention has reference to improvements in automatic pumps and isdesigned to utilize the force generated by the ignition of an explosivemixture for causing the elevation of water or other liquids and at thesame time the generation of motive power by the said explosive mixture.

In accordance with the present invention there are providedcommunicating explosion chambers in one of which is located a pistoncapable of reciprocation and utilized for the driving of a suitableshaft whereby power may be generated and transmitted to the point ofutilization, and the other explosion chamber is in operative relation topumping mechanism whereby the force of the explosion is utilized tocause the raising of'water or other suitable liquid of which water maybe taken as typical, to a desired height.

The invention also includes an air bell with means for maintaining theair pressure therein constant.

The invention will be best understood from a consideration of thefollowing detail description taken in connection with the accompanyingdrawings, forming a part of this specification, in which drawings,

Figure 1 is a perspective view of the improved automatic pump, Fig. 2 isa central vertical section therethrough with parts shown in elevation.

Referring to the drawings there is shown a basic member 1 designed to beset on a suitable foundation and this basic member in closes a chamber 2divided into a series of compartments by webs or diaphragms 34.

Entering the compartment inclosed by the web 4 is a pipe 5 coming fromany suitable source of water supply. Through the Web 4 are formed aseries of perforations 6 each normally closed by a valve 7 pressed toits seat by a spring 8 so that each valve 7 will yield to a forcesuperior to the strength of the spring to unclose the respective openingor passage 6.

Through the web 3 are like passages 9 each normally closed by a valve 10held to its seat Specification of Letters Patent.

by a spring 11 and only yielding to uncover the passage 9 by theexertion of a force superior to the strength of the spring.

In the particular showing of the drawings the valves open upwardly sothat water entering through the pipe 5 will find itsway into the mainchamber 2 through the valves 6 and from the chamber 2 water will findits way through the passages 9 to the compartment inclosed by the web 3.Leading from the last named compartment is a pipe 12 which may rise toany height within the capacity of the apparatus and there discharge intoa reservoir or be otherwise utilized.

Rising from the base 1 at a point above the web 1 is a cylinder 13 andsecured to the upper end of this cylinder is another cylinder 14k inalinement therewith but separated theretrom by a dividing web ordiaphragm 15.

The lower end of the cylinder 13 is coincident with a passage 16 ofequal diameter leading into the chamber 2 through the top of the casingwhile the upper end of the cylinder 14 is open.

1V ithin the cylinder 14; there is housed a piston '17 of the ordinarytrunk type and rising from the upper end of the cylinder 14: arestandards 18 in which are formed journal bearings for a crank shaft 19carrying at each end balance wheels 20 while the crank shaft isconnected to the piston 17 by a pitman 21,, all these parts beingsimilar to those used in explosive engines. So far as the explosionengine side of the device is concerned it may follow the usual practicein. four-cycle engine construction.

Both cylinders13 and 14 are provided with water jackets 22 which jacketsmay be intercommunicating and are connected near their lower ends by apipe 23 to the lower end of the pipe 12 and near their upper ends by apipe 21 entering the pipe 12 at an appropriate height, this arrangementproviding circulation sufficient to maintain the cylinders workablycool. At one side of the two cylinders 13 and 14 is a valve chest 25having in the present instance four valves 26, 27, 28 and 29 each valvebeing held to its seat by a respective spring 30.

The several valves are under control of operating levers 31independently mounted on a post 32 rising from a bracket 33 secured tothe cylinder 13 and these arms 31 are operated in proper sequence andphase relation by a cam shaft 34 journaled in bearings on the cylinders13 and 14 and receiving motion through an appropriate gear driven by thecrank shaft 19.

The valves 20 and 29 are exhaust valves while the valve 27 is an inletvalve for the explosive mixture for the chambers within the cylinders 14and 13 respectively, and the valve 28 is provided for a purpose whichwill presently appear.

Vithin the cylinder 13 between the ports of the valves 28 and 29 is adeflector plate 36 such as is commonly used in two-cycle enginecylinders.

Above the web 3 the base 1 carries an air bell cylinder 37. In thestructure shown in the drawings the cylinder 37 is in free communicationwith the compartment above the web 3 and within this cylinder there ismounted a float 38 on the lower end of a stem 39, the upper end of whichlatter projects through the upper end of the cylinder and inside thelatter carries a valve 40 adapted to enter a valve seat 41 on the innerface of the top of the cylinder. The lower end of the valve rod 39projects below the float 38 and there passes through a guide 42appropriately supported in the cylinder or air bell. There is alsoprovided a suitable igniter which is diagrammatically typified at 43.

Let it be assumed that the head of water coming through the pipe 5 issufiicient to cause the water to reach the level in the cylinder 13about that indicated in the drawings, and let it also be assumed thatthe shaft 19 is rotating and the piston 17 is reciprocating.

At a certain period during the reciproca tory movement of the piston 17an explosive mixture is drawn in through the valve 27 which at thisinstant is positively opened by the appropriate lever 31 and the cam onthe cam shaft 34. The next movement of the piston in the directioncontrary to that causing the inflow of the explosive mixture willcompress this mixture in the cylinders 13 and 14 and during this timethe valve 28 is open. At the proper time the igniter 43 is caused tooperate and the mixture is ignited, the flame passing through theopening at other times closed by the valve 28 and from this opening intothe cylinders 13 and 14.

The explosion within the chamber 14 causes the forward or power strokeof the piston 17 in a manner such as is common in explosion engineswhile the explosion in the chamber 13 is exerted against the surface ofthe water since this chamber is separated from the cylinder 14 by theweb or diaphragm 15. The force of the explosion within the cylinder 13will force the water against. the valves 6 closing the same and willalso force the water through the openings 9 and past the valves 10 andinto the chamber above the web 3, the water passing into the air belland also into the pipe 12,

the action in this respect being similar to that of the ordinary pump.The return stroke of the piston 17 is the scavenger stroke and the camshaft causes the opening of the valves 26 and 29 which are the exhaustvalves of the respective cylinders 14 and 13. On the next forward strokeof the piston 17 a fresh charge is drawn in through the valve 27 and onthe compression stroke of the piston this charge is compressed andexploded in both cylinders as before.

More or less air is carried into the compartment above the web 3 by thewater and finds its way into the air bell 37. The result of this is thatthe level of the water in the air bell. lowers and the valve 33 followsthis lowering level of the water. As the float 3S lowers the valve 40 isdrawn away from the valve seat 41 and the air within the air bell findsescape through the passage for the rod 39 through the head of the airhell. The result of this is that the water level in the air bellimmediately rises and the float following it causes the closure of thevalve 40 against its seat 41 thus preventing the admission or the escapeof any more air and this condition continues until air or gases carriedover by the water into the compartment above the web 3 accumulatessufiiciently within the bell 37 to again cause lowering of the level ofthe water therein and the opening of the valve 40.

By the apparatus described water may be elevated in quantities dependingupon the size and power of the apparatus and at the same time motivepower is supplied to the shaft 19 and from thence may be transmitted toany point of utilization so that the device becomes a combined powerengine and pump of the explosion type.

The igniter 43 may be of any suitable type and is controlled by theengine after the manner common in explosion engines and so this igniterand means for controlling the same have been omitted from the drawingssince both the igniter and the means for causing it to act form no partof the present invention.

The valve 28 serves to prevent the access of water to the igniter shouldthe water splash high enough when entering the cylinder 13. The twocylinders because of the lDtGFCOHlDlllIllCtlt1011 between them becomepractically simultaneously filled with the charge, but because of thesmall size of the inter-connection each cylinder becomes to a greatextent, independent of the other so that the burning of the charge inthe cylinder containing the piston causes the power stroke of the latterwhile the burning of the charge in the cylinder containing the 'lvateroperates on such water to drive it out of the cylinder into the air belland into the conduit leading therefrom.

hat is claimed is 1.
